Hi Kim
I am 32 and am a pre-bander, I approched my GP just over 4 years ago and was put on xenical I lost a couple of stone and then got pregnant and then went back on xenical when my son was born. I have lost a bit and joined a gym which also helped quite a bit BUT as I say I am waiting for a band as in teh end the tablets are ok while you are on them and as soon as you stop taking them you put the weight back on. My advice is to speak to your gp honestly and listen to what they say, depending where you are will depend on teh route to wls. You will I think be put on some kind of weight loss drug to see if they work. In the end you can only tell your gP how you feel and how being overweigt makes you feel, I started off at 20stone 5 and at 5ft4 so my BMI was around 48 I think which is pretty high.
Good luck what ever you choose x
